properties of ribofuranosyl N-phenyltrifluoroacetimidates toward carboxamide sidechains of asparagine and glutamine were investigated. Conditions were found that promote nearly exclusive formation of the α-anomerically configured N-glycosides. The strategy allows for the synthesis of Fmoc-amino acids suitably modified for the preparation of ADP-ribosylated peptides. Furthermore, ribosylation of serine with

variety of cellular processes. To study the enzymes responsible for the establishment, recognition, and removal of this PTM, stable analogues are invaluable tools. We describe the design and synthesis of a 4-thioribosyl APRr peptide that has been assembled by solid phase synthesis. The key 4-thioribosyl serine buildingblock was obtained in a stereoselective glycosylation reaction using an alkynylbenzoate
